Study of the relationship between tortuosity of vertebrobasilar artery and posterior circulation ischemia
摘要
Abstract
Objective:To investigate the relationship between posterior circulation ischemia ( PCI) and circuity and tortuosity degree of vertebrobasilar artery. Methods:A total of 205 patients with posterior circulation ischemia were included. An additional 108 subjects were concomitantly enrolled as controls. We investigated by using VCTDSA in all subjects. First,the circuity of vertebrobasilar arteries were observed and angle of these circuity were measured on VR images in both group. Then,according to numbers and angle of tortuosity,tortuosity degrees were estimated. Finally,the correlation between circuity degrees of vertebral-basilar artery and PCI were an-alyzed. Results:Significant differences of the incidence of left and right vertebral artery and basilar artery were found between patients with PCI and controls (χ2 =66. 860,P P=0. 000;χ2 =43. 457,P=0. 000;χ2 =19. 203,P=0. 000). The circuity degrees in PCI was significantly higher than that in controls,showing a significant difference (χ2 =91. 115,P=0. 000;χ2 =86. 620,P=0. 000;χ2 =43. 371,P=0. 000). PCI has correlation with the circuity of vertebral artery (r=0. 49,P=0. 000). There is a moderate correlation be-tween circuity level Ⅲor higher of vertebral artery and PCI (r=0. 65,P=0. 000). PCI has correlation with the circuity of basal artery (r=0. 25,P=0. 000). There is a weak correlation between circuity level Ⅲ or higher of basal artery and PCI(r=0. 37,P=0. 000). Conclusion:The circuity of vertebrobasilar arteries may lead to PCI,especially circuity level Ⅲ or higher.关键词
